ROME (AP).- Authorities say a magnitude 4.2 earthquake has shaken the Italian region of Umbria but caused no injuries.

Towns in the province of Perugia reported buildings lightly damaged by the temblor, monitored by Italy's national institute of geophysics.

Italy's agriculture minister said Tuesday 600 people were evacuated until their homes can be inspected. Mayors of several hamlets ordered schools closed Wednesday for inspections.

Video of the city of Perugia showed bricks in the street and some damage to walls. The American student Amanda Knox, convicted this month of murdering her British roommate, is in Capanne prison outside Perugia.

In April, a quake hit the Abruzzo region in central Italy, killing about 300 and leaving tens of thousands of homeless.
